A minor point is that if you buy the Admiral shares of the Vanguard Total Stock Market Index (VTSAX) the expense ratio drops from .17 to .05 basis points. The minimum investment is only 10K.

Also, why wouldn't you just buy (VT), Vanguard Total World Stock ETF? Do you think it is better to limit yourself to just U.S. stocks or do you get enough world diversification because a lot of U.S. companies conduct business abroad. I know this is an argument Bogel makes, although Vanguard slightly disagrees with him. Thanks for any response.
